Estimation of some heavy metals concentration in layer farms at el-Fayoum governorate

الملخص EN

The objective of this work was to estimate the lead (Pb), Cadmium (Cd), Copper (Cu), Zinc (Zn), Iron (Fe) and Manganese (Mn) contents in drinking water, layer feed and in addition Hen's Eggs collected from two layer farms which present at two different areas, non industrial area (Integrated poultry project in El-Azab) and industrial area (Kom Oshim) in Tamia district in El-Fayoum province, Egypt, during winter season.

All samples will be analyzed to determine the translocations of heavy metals from water and feed to the bird's eggs.

The results explained that the mean metal contents in the different samples of selected poultry farms are Pb (0.436±0.26, 0.529±0.089), (2.891±0.194, 3.182±0.28) and (0.071± 0.03, 0.099±0.0396 ppm).

Cd (0.2912±0.029, 0.3936±0.013), (0.508±0.017, 0.5854±0.003) and (0.005±0.0013, 0.0125±0.003 ppm).

Cu (4.651±0.044, 4.1352±0.288), (9.15±1.202,14.75±0.417) and (0.0442±0.0075, 0.03032±0.004 ppm).

Zn (55.238±0.386, 57.739±0.466), (57.605±3.06, 58.319±0.73) and (0.0668±0.018,0.016±0.00498 ppm).

Fe (309.49±44.015, 291.553±0.466), (153.58±15.3, 124.12±3.26) and (0.013±0.008 ppm , ND).

And Mn (2.63±0.3049, 2.178±0.191), (84.98±5.676, 85.884±1.07) and (0.0056±0.0037 ppm , ND) for eggs, layer feeds and drinking water which were collected from non industrial area and industrial area in El-Fayoum province, Egypt, respectively.

These data interpreted that Pb and Cd in eggs, layer feeds and drinking water collected from industrial area were higher than that which were collected from non industrial area.

Also these metals residual concentrations particularly in layer eggs and drinking water were more than the permissible limits
